ABSTRACT:
Rainbow technology,a breakthrough in digital data storage enables us to store up to a massive 450GB on just a piece of paper. Rainbow Storage is a group of techniques to store digital data known in as some rainbow colors, format, color and combinations and some symbols therefore a rainbow picture will be generated. The technique is used to achieve high-density storage. With the help of Rainbow system we would be watching full-length highdefinition videos from a piece of paper! The main attraction is the cheap paper. The Rainbow technology is feasible because printed text, readable by the human eye is a very wasteful use of the potential capacity of paper to store data. By
printing the data encoded in a denser way much higher capacities can be achieved. Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of paper also cost a fraction of the cost of a CD or DVD. This boon to digital data storage is developed by Sainul Abideen, university technology student at the Muslim educational society Engineering College in Kerala.

HOW IS IT POSSIBLE

Data stored in rainbow format on an ordinary paper. It uses geometric shapes such as squares and hexagons to represent data patterns, instead of the usual binary method that uses ones and zeros to represent data. Besides, color is also used in the Rainbow system, to represent other data elements. Files such as text, images, sounds and video clips are encoded in "rainbow format" as colored circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch.

scanner and specialized software. Smaller scanners could fit inside laptop computers or mobile phones, and read SIM card-sized RVD's containing 5GB of data. The recording media could be either paper or plastic sheets. The piece of paper or even plastic sheet storing the data has just to be scanned in the scanner and read over the monitor. A scanning drive based on the Rainbow software has simultaneously been developed which will come in smaller sizes to be initially carried with the laptops and later to fit into their bodies. The developer is simultaneously moulding the technology into 'Rainbow Cards' which will be of SIM card size and store 5 GB of data equivalent to three films of DVD quality. As 'Rainbow Cards' will become Popular, Rainbow Card Readers
will replace CD drives of mobile phone and computer notebooks and will enable more data in portable forms for mini digital readers. Large scale manufacture of the Rainbow card will bring down its cost to just 50 paise DEMONSTRATION: DEMONSTRATION:
Sainul Abideen, the developer, explaining feature of his brainchild -Rainbow Technology The reporter of Arab News claims to have seen 450 pages of fully printed foolscap being stored on a 4-square inch piece of Rainbow paper. The reporter also claimed

that he was shown a 45-second video clip that was stored using the Rainbow system on a plain piece of paper. Abideen has demonstrated a 45-second video clip being encoded on paper, termed by him, a rainbow video disk - RVD - and then played back through a computer with an RVD scanner attached. In another demonstration he has shown 432 A4 pages of paper rainbow formatencoded and stored on a two-inch by two-inch square of paper. CD, DVD?s a thing of past. Currently, of the several options available for data storage, DVDs are the best mode, but are yet expensive. Sianul has said that a CD or DVD consumes 16gms of polycarbonate, which is a petroleum by-product. While a CD costs Rs. 15, his paper or plastic-made RVD will cost just about Rs. 1.50 and will even have 131 times more storage capacity. Using this technology an A4 sheet COMPARISON WITH OTHER STORAGE DEVICES: of paper could store 256GB of data. In comparison, a DVD can store 4.7GB of data.
Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of paper also cost a fraction of the cost of a CD or DVD.

He biodegradable nature of the storage devices would do away with the e-waste
ADVANTAGES: ? Data can be stored on an ordinary paper. ? Abideen claims that huge data banks can be constructed out of Rainbowbased storage medium. ? Larger amount of data can be had on lesser space. ? The extremely low-cost technology will drastically reduce the cost of storage and provide for high speed storage too. ? Files in any format like movie files, songs, images, text can be stored using this technology.
pollution. ? The four main storage devices made using this technology are RVD, Disposable storage, Data Banks, Rainbow cards, and answer to the storage problems faced by the computer world. ? With the help of disposable storage,a high density data storage is made possible even on paper or plastic sheets,any type of computer files can be stored and distributed this way,so instead of giving cd?s with the computer magazines,its content can be printed in a page,video albums, software etc.Can be

distributed at avery low cost with the help disposable storage ? Rainbow cards can be used in mobile devices in place of DVDs &VCDs.In a square inch sized rainbow cards, (equivalent to the size of sim card)more than 5GB data can be stored.A major crisis faced in the design of the small digital devices is the huge size of the CD/DVD drives.The rainbow cards can solve this problem.Unauthorized copies of the films can be controlled to a certain limits using these cards.A UK-based company has already evinced interest in making rainbow cards ? Another theme put forward by rainbow technology is the Data
Banks;it is huge server with a high storage capacity.As per a research project done in US in 2003 to store the avaible static data(films,songs,tutorials presentations etc)the server required will cost $500 crores(23000 crores).But by using data banks ,a similar server can be made with Rs.35 lacks.All;the available films and other static data can be used by paying cash with the internet.Almost 125.603 PB data storage is possible in a Data Bank. ? Sainul is busy with project Xpre3ssa now.It?s a software package for regional languages.By using this, News papers, stories, novels etc can be made audible in it?s own style.so online news papers and

novels can be enjoyed through mobile phone with a GPRS connection.Sainul Abideen, a native of Karingappara , is a freelence software developer.

popularity of the Rainbow Technology, computer or fashion magazines in future need not carry CDs in a pack. One of the major advantages of the Rainbow system is the fact that it should cost a lot less to produce than the typical polycarbonate DVDs, CDs and now Blu- rays. Huge data banks can be
Un-authorized copies of the films can be controlled to a certain limit using these cards.
DISADVANTAGES: The paper has the tendency to fade away hence the data loss may occur.

With the extremely low cost of using this technology we can always afford to have multiple copies. CONCLUSION: Once the Rainbow technology is in, soon we would be watching full-length high-definition videos from a piece of paper! With the 1. "Data Can Now Be Stored on Paper" by M. A.
